Ukip’s parliamentary spokesperson Suzanne Evans has listed an abundance of reasons why Britain’s post-Brexit future is looking bright after a predicted uncertain first day of independence.

In a Facebook post lauded by Leave voters, Ms Evans noted how both the pound and FTSE 100 both recovered from yesterday’s early falls, while pro-EU campaigners had now backtracked on pre-referendum ‘Project Fear’ scare stories.

She wrote: “If this was the predicted apocalypse, well, it was a very British one.

Tottenham MP David Lammy was accused of “haughty disregard” for voters after telling his fellow MPs to “stop this madness and bring this nightmare to an end through a vote in Parliament”.

Europe says ‘get out now’

It cam as France today ordered Britain to appoint a new Prime Minister within “a few days” as the founding members of the EU ganged up to tell the UK to urgently quit the bloc following the Brexit vote.

German Foreign Minister Frank-Walter Steinmeier warned Britain to act quickly to leave the EU by soon triggering Article 50 of the Lisbon Treaty – the formal legal process by which the UK will extract itself from the bloc.

He said: “We join together in saying that this process must begin as soon as possible so we don’t end up in an extended limbo period but rather can focus on the future of Europe and the work toward it.”

France’s foreign minister Jean-Marc Ayrault backed those calls and demanded Britain choose a new prime minister in the next week.

David Cameron yesterday announced his intention to stand down as Prime Minister but signalled he will carry on in Downing Street for the next three months.

He also said he will leave it to a new premier to choose when to invoke Article 50.

But Mr Ayrault said: “A new prime minister must be designated, that will take a few days.”

But German Chancellor Angela Merkel contradicted those claims by saying there was no hurry for Britain to invoke Article 50.

She said: “It should not take ages, that is true, but I would not fight now for a short time frame.”

The German leader also called for negotiations to “take place in a businesslike, good climate”, adding: “Britain will remain a close partner, with which we are linked economically.”
